Detailed Product Description

EMI/RFI Filter:

Electromagnetic Interference or EMI is a type of energy. EMI is often used interchangeably with RFI, Radio Frequency Interference, but technically RFI is the frequency range of the noise and EMI refers to the type of energy, electromagnetic. Electromagnetic energy produces interference, or noise, which is everywhere. It is created by lightning, rain, and even wind.

Interference is removed by the filter. EMI and RFI filters have a specified range of unwanted signals, noise, which is blocked. The filters have a circuit with a series of inductive and parallel capacitive mechanisms, also known as load-bearing and non-load bearing components, to do this.

There are a few different EMI filter phases that can exist, a single phase, a three-phase or DC. Single phase and three phase are both types of alternating current (AC) and direct current (DC) is a current that always travels in the same direction. EMI filters are rated with voltage (designed voltage), current (designed current) and insertion loss (its attenuation information, in decibels, dB), which is the ratio of noise without the filter to the noise with the filter installed.
